You can use the ``[]`` operator to access elements by index. This operator will raise an :py:exc:`IndexError` if you try to access a nonexistent frame. :param im: An image object. c � � t |d� � sd}t |� � �|| _ t | j dd� � | _ d S )N�seekzim must have seek method� _min_frame� )�hasattr�AttributeError�im�getattr�position)�selfr �msgs �3/usr/lib/python3/dist-packages/PIL/ImageSequence.py�__init__zIterator.__init__ sG � ��r�6�"�"� &�,�C� ��%�%� %���� ��� �q�9�9�� � � � c �z � | j � |� � | j S # t $ r }t |�d }~ww xY w�N)r r �EOFError� IndexError)r �ix�es r � __getitem__zIterator.__getitem__& sI � � $� �G�L�L�� � � ��7�N��� $� $� $� �!� #����� $���s � # � :�5�:c � � | S r � )r s r �__iter__zIterator.__iter__- s � �� r c � � | j � | j � � | xj dz c_ | j S # t $ r }t |�d }~ww xY w)N� )r r r r � StopIteration)r r s r �__next__zIterator.__next__0 s[ � � '� �G�L�L�� � '� '� '� �M�M�Q� �M�M��7�N��� '� '� '� �Q� &����� '���s �58 � A�A � AN)�__name__� __module__� __qualname__�__doc__r r r r r r r r r sZ � � � � � � � �:� :� :�$� $� $�� � �'� '� '� '� 'r r Nc �� �� t | t � � s| g} g }| D ]G}|� � � }|d� t |� � D � � z }|� |� � �H�r�fd�|D � � n|S )a Applies a given function to all frames in an image or a list of images.
